- " Vim syntax file
- " Language: Perl POD format
- " Maintainer: Andy Lester <andy@petdance.com>

-
- " To add embedded POD documentation highlighting to your syntax file, add
- " the commands:
- "
- " syn include @Pod <sfile>:p:h/pod.vim
- " syn region myPOD start="^=pod" start="^=head" end="^=cut" keepend contained contains=@Pod
- "
- " and add myPod to the contains= list of some existing region, probably a
- " comment. The "keepend" flag is needed because "=cut" is matched as a
- " pattern in its own right.
-
-
- " Remove any old syntax stuff hanging around (this is suppressed
- " automatically by ":syn include" if necessary).
- " For version 5.x: Clear all syntax items
- " For version 6.x: Quit when a syntax file was already loaded
- if version < 600
- syntax clear
- elseif exists("b:current_syntax")
- finish
- endif
